Assessment on the seismic and tectonic aspects of naturalcatastrophe in Indonesia has been carried out. Special attention has been paid oncommonly occurring and disastrous earthquakes. To locate the epic entre, depth andmagnitude of the earthquakes, seismic data from seismic station is employed. Thesetting up of auxiliary seismic stations of CTBT in Indonesia includes the provision ofbroadband-sensor communication system based on basic topology configuration. Theyare located in six different locations to support national seismic nenvork, which is anelement in the international monitoring system. P.l. Prih HarjadiMeteorological and Geophysical Agency.
